    perf: make sure we emit finished after last process exits
    
    This fixes the "auto-stop" feature when the child exits, at least in the
    case of /usr/bin/gnome-calculator. However, when testing with gedit I
    did not see it accurately clean up, so something still needs to be
    troubleshooted.
